Allen 1998 A qualitative analysis of the process, mediating variables and impact of traumatic childbirth. UK	Sample size 20 Selection process Recruitment via health visitor routine check-up 8 months PC. Stage 1: assess level of perceived distress in labour. Stage 2: interview women who found labour extremely distressing. Rationale Recruit larger number of women, including those not only attending due to problems. Drop-outs 223 check-ups, 145 took part in 1^st stage, 26 met incl. criteria for stage 2, 23 consented, 2 moved away and 1 changed her mind. Ethical Approval Local health district. Info provided and consent obtained.	Goal Explore distressing aspects of labour - the subjective experience. Why important Minimal previous work on subjective experience relevant to postnatal psychological state. Relevance Developing knowledge about PTSD-PC.	Measure of PTSD States IES-R, but references IES (Horowitz, Wilner, & Alvarez, 1979) 8 months PC. 8 with PTSD-PC 6 women score > cut-off 42 and 2 women score borderline =41. Note higher cut-off values than the suggested 33 for IES-R, resulting doubt onto the actual tool used, and the appropriateness of the cut-off values	Method Qualitative. Design Grounded Theory. Data collection Semi-structured interviews. Questions developed from pilot study. Collection technique Audio-taped and transcribed. Rationale Qualitative data provide richer more elaborate study of exploring experience. Grounded theory more structured. Analysis Exploratory framework based on Strauss and Corbin paradigm model. Used axial and selective coding. Reflexivity and reflection Not discussed. Saturation Not discussed, fixed sample size.	Clear statement of findings Lack of control due to: staff errors, staff panicking or too busy, dismissive, lack of communication, poor pain relief, being ignored, unmet expectations and lack of support. Lack of support also led to feeling isolated and abandoned. Receiving support reduced distress. Consistent with other findings PTSD related to threat of harm. Subjective interpretation influences perception of trauma. Inaccurate expectations may lead to shock. Discussion of findings Findings can be explained in the framework of the psycho-social model of PTSD (Green, Lindy, & Grace, 1985) Limitations noted Small sample, no comparison between trauma and non-trauma	CASP rating High Value of study Adds to growing awareness of PTSD-PC and related complex causes. implications Optimise support, sense of control. Increase provider awareness of PTSD-PC. Take account of PTSD-PC during AN education and need for treatment.
Anderson and McGuinness 2008 Do Teenage Mothers Experience Childbirth as Traumatic? USA	Sample size 28. Aged 15-19. Selection process Random sample of women previously attending a nursing educational program, spoke English, had a telephone. Rationale Not stated. Drop-outs n/a Ethical approval University board. Info provided and consent obtained – not described.	Focus Assess symptoms of PTS and PND. Also measured subjective experience. Small focus on QPI. Population Teenage, childbearing women.	Measure of PTSD IES (Horowitz et al., 1979). Timing not stated but assumed to be at same time as interview - 9 months PC, to coincide with peak time of PTSD. Cut-offs used: 19-25 mild PTS, 26-34 moderate PTS. No one had over 34. EPDS was also used at the same time as the IES.	Method Quantitative, Pilot Study. Subjective measure Likert scales. Objective measures Mode of birth (22 SVB, 6 non-specified, non-SVB) Blinding used n/a Data collection Telephone Interview. Confounding factors Does not record history of PTS. Analysis Descriptive summary statistics.	Results Fear (28), anxiety (27), midwives kind (23) supportive (26), experience ‘awful’ (worst rating) (4). Application to local population Teenage mothers in this area of USA. Fit with other findings High % of positive perception of midwives, inconsistent with other findings, may be due to particular care of teenage mothers. Discussion of findings Some teenage mothers are vulnerable to PTSD. Limitations noted Lack of knowledge re previous PTS.	CASP rating Low Implications for practice For teenage women, assessing previous trauma and providing positive midwife support, and involvement in decision making may reduce psychological sequelae of childbirth.
Ayers 2007 Thoughts and Emotions During Traumatic Birth: A Qualitative Study UK Ayers 2007continued	Sample size 25 with PTSD-PC, 25 without PTSD-PC, matched by obstetric factors. Selection process Subsample from longitudinal study Rationale PTSD group scored above cut-off of 19 on either scale at 1 and 6 weeks PC. Drop-outs PTSD group: 38 met incl., 28 consented, 3 had data recording errors. Non-consenters had more avoidance. Non-PTSD group: no drop outs Ethical approval Obtained in original study. No mention of info provided or consent obtained.	Goal Explore non-medical aspects of birth experience, thoughts, emotions, memories. Why important Lack of previous research. Relevance Developing knowledge about PTSD-PC.	Measure of PTSD IES (Horowitz et al., 1979) and PSSS (Foa, Riggs, Dancu, & Rothbaum, 1993), adapted to reflect childbirth as the traumatic event. Cut-off used was 19 for either scale Assessed at 1 and 6 weeks PC. Did not assess Criterion A of DSM-IV, so referred to women having PTS symptoms rather than PTSD.	Method Qualitative. Design Not explicit. Data collection Face-to-face interview at 3 months PC Collection technique Audio recorded and transcribed. Rationale Qualitative is most appropriate to understand range of thoughts and emotions. Analysis Thematic analysis, coding. Reflexivity and reflection Not described specifically, although transcripts were checked by a second researcher.	Clear statement of findings Women with PTS: poor understanding of what was going on, unmet expectations, anger. Women with and without PTS: lack choice, panicky, wanting all to stop (more when PTS).Women without PTS: unaware of seriousness, upset at staff behaviour or treatment, sense of control, sense of acceptance. Consistent with other findings Anger associated with general PTSD. Discussion of findings midwives must attend to women’s emotional state during birth to minimise negative emotions and perception of life threat. Limitations noted Did not measure criterion A of DSM-IV.	CASP rating Moderate Value of the research A detailed glimpse into thoughts and emotions of women during birth, highlighting some that occur more in women with PTSD. Implications midwives being more aware of PTSD and potential signs and provide care to minimise risk.
Ballard et al. 1995 Post-Traumatic Stress Disorder (PTSD) after Childbirth UK	Sample size 4 Selection process Convenience sample of case reports for subjects with stress reactions after delivery. Rationale Describe the clinical picture and course of disorder of stress reactions PC. Drop-outs n/a Ethical Approval Not stated.	Goal To further explore the link between PTSD and childbirth. Why important Earlier studies suggest a link, which may be a concern. Relevance An early seminal piece of work, widely referenced in the PTSD-PC literature	Measure of PTSD The paper relates the symptom profiles to that of PTSD. No formal assessment tool described.	Method Qualitative. Design Case Study. Data Collection Cases arising requiring psychological care. Collection technique Written accounts of individual case histories. Rationale Not given. Analysis Descriptive. Reflexivity and reflection None described.	Clear statement of findings All had elements of PTSD. 3 describe being left alone, unsupported, lack of pain relief. 1, with objectively good outcome, describes being ignored, dismissed, overruled by punitive midwives, whilst lacking confidence in midwives’ knowledge. 2 expressed anger and rage towards midwives. Consistent with other findings Ground breaking early study, consistent with other early observations and studies. Discussion of findings Confirms lack of control a consistently important feature. Limitations noted Small sample	CASP rating Low Value of the research Confirms further a link between PTSD and childbirth, prompting need for further research. Implications Suggests prompt apology after adverse events might avert some incidence.
Beck 2004 Birth Trauma In the Eye of the Beholder New Zealand (n=23), USA (n=8), Australia (n=6), UK (n=3).	Sample size 40. Selection process Purposive sample of women who perceived they had experienced birth trauma. Length of time since traumatic birth 5 weeks to 14 years. Rationale Gain perspective from those who had experienced the phenomena being studied. Drop-outs n/a Ethical Approval University review board. Participant Info provided and consent received	Goal Explore essential structure of women's experience of birth trauma. Why important Growing knowledge of PTSD-PC, need to understand features of totality of subjective experience of childbirth. Relevance Developing knowledge re PTSD-PC.	Measure of PTSD Not specified. Women self-stated birth was traumatic. Study states 32/40 had diagnosis of PTSD and 8 had PTS symptoms but had not yet sought mental healthcare. No details re means of diagnosis.	Method Qualitative. Design Descriptive Phenomenology. Data collection Women submitted, written birth stories. Collection technique Via internet or post. Rationale Exploring experience. Analysis Colaizzi’s thematic analysis (1978). Reflexivity and reflection Husserl’s bracketing referenced, but not made explicit re use in the study	Clear statement of findings Feeling abandoned and alone, stripped of dignity, lack of consent, felt like a battlefield. Midwife uninterested, being ignored, dismissed.Lack of support - especially when fearful. Lack of midwife communication with women and other midwives. Perception of unsafe care led to fear, powerlessness and shattered expectations of safe care. Being uninformed led to lack of trust in midwife. Words used about care: mechanical, arrogant, cold, technical, raped. Consistent with other findings Consistent with other findings re types of birth trauma. Discussion of findings n/a.	CASP rating Moderate Value of the research Increases understanding of subjective experience. Implications need good history taking re birth trauma, enhance sense of control, address unmet expectations, be alert to early signs of trauma. Treat all women as though a survivor of trauma.
Cigoli et al. 2006 Relational factors in psycho-pathological responses to childbirth Italy	Sample size 160 recruited sequentially. Sample represents defined population Yes, pregnant women in late pregnancy or new mothers. Drop-outs Sequential process, meant no drop-outs, 160 returned the questionnaires with at least 75% completed. Ethical Approval States process of providing information re the study and gaining consent. But source of ethical approval not specified.	Focus To examine how support relates to stress symptoms of PTSD. Population Age over 18, at least 39 weeks pregnant, or have had healthy baby, and have no psychiatric diagnosis.	Measure of PTSD PTSD-Q (Czarnocka & Slade, 2000) adapted to reflect childbirth as the traumatic event, at 48 hours and 3-6 months PC, used to categorise into two groups. Also BDI, EFS, STAI, Perceived Desire and Support Scale (PDSS).	Method Observational study, selected cohort, mixed methods comparing 2 groups. Non-risk (no PTSD) n=112, risk group (partial, n=46 or full PTSD, n=2). Subjective measures Subjective assessment scales. Article states there is an interview, but interview data not presented in this paper or referenced. Objective measures Demographics using Anamnestic Schedule. Blinding used n/a. Data collection Survey and semi-structured interview Confounding factors Not discussed. Analysis Correlation statistics, Mann-Whitney and Rho of spearman. Comparisons using t-test. No details re analysis of interviews	Results Only quantitative results presented, discussed. Factors which contribute significantly to PTSD-PC: Unmet desired support from midwife. However, perceived support from midwife is not significant. NB only 2 participants had clinically significant PTSD, 46 had varying levels of PTS symptoms, 112 had no symptoms. Application to local population Yes, local childbearing women. Fit with other findings Yes, in terms of support being important. Discussion of findings PTSD is a complex situation, but higher scores are associated with stronger desire for support, often then perceived as not being met. Limitations observed Finding re support and PTSD, are only small part of the study.	CASP rating Moderate Implications for practice Effective social interventions, need targeted consultation at end of pregnancy and early parenthood with both mother and her potential support network.
De Schepper et al. 2015 Post-Traumatic Stress Disorder after childbirth and the influence of maternity team care during labour and birth: A cohort study Belgium	Sample size 340 women in first week 229 women at 6 weeks. Sample represents defined population Yes, random sample from across 13 maternity postnatal wards. Drop-outs 420 invited, 340 agreed to first phase and of these 229 agreed to the second phase. The cohort of 340 and the cohort of 229 were similar demographically and in terms of PTSD. Ethical Approval Antwerp University Hospital. Info provided and consent obtained.	Focus Main focus is role of midwifery team care factors, also examines Prevalence of PTSD and personal and obstetric factors. AIM to inform midwives about PTSD as a possible postpartum complication. Population Age > 18, Dutch Speaking. Excluded stillbirth, pre-term <24 weeks and intrapartum psychosis.	Measure of PTSD At 1 week (day1-4) and 6 weeks IES-R (Weiss & Marmar, 1997) (cut-off = 24) and the TES (Wijma, Söderquist, & Wijma, 1997) Designed for general PTSD (cut-off is not specified). PTSD assessment questionnaires completed a few days after birth and at 6 weeks, via telephone call or email.	Method Quantitative Prospective Cohort study. Subjective measures Likert scales MW team care for perception of fear, experience of birth, care received, admission process, level of info, freedom to ask questions, trust in and respect for midwife, support, reassurance, respect, locus of control, perception of team being in control, and participation in birth process. Objective measures Demographics, mode of birth, complications, medical and obstetric history. Blinding used n/a Data collection A few days after birth: Questionnaire- Demographics, medical and obstetric history and midwifery team care. Confounding factors Accounted for in focus. Analysis Descriptive, t-tests, one-way ANOVAs, X^2 tests, Mann Whitney U, Spearman rank, multiple linear regression, and logistic regression.	Results At 6 weeks, factors which contribute significantly to lower PTSD-PC: perception of midwife being in control, being able to ask questions. Application to local population Good sample size representing a balanced snapshot of Belgian childbearing women. Fit with other findings Consistent with other findings re importance of internal locus of control by being able to ask questions. Discussion of findings Rate of PTS symptoms reduced between 1 and 6 weeks. PTSD at 6 weeks 0% (IES-R) and 4% (TES). Being able to ask questions is protective of PTSD as 6 weeks. Limitations Data collected at 6 weeks, PTSD symptoms may decline by 3 months. Different scores on IES-R and TES, possibly TES takes account of more DSM-IV criteria. Telephone/email data collection may bias results. Excluding women with language barrier, may underestimate PTSD.	CASP rating High Implications for practice First assessment of MW team care factors. Can be influenced by MW. Calls for research into QPI. Highlight PTSD-PC to MW and medical students. MWs need to be aware of the impact of care provision on woman’s well-being. Take caution with interventions to let the women be in control as much as possible.
Ford and Ayers 2011 Support during birth interacts with prior trauma and birth intervention to predict postnatal post-traumatic stress symptoms UK	Sample size 138 Sample represents defined population Recruited from UK NHS Maternity units. Drop-outs 215 recruited, 138 completed at least one questionnaire: at 33-37 weeks pregnant (136); at 3 weeks PC (125); at 3 months PC (109). Only demographic difference between responders and non-responders was responders had fewer children. Ethical approval University research governance committee and NHS local research ethics committee. No mention of info given or consent obtained	Focus Role of midwife support and personal control during birth as predictors of PTSD-PC whilst controlling for previous trauma, antenatal depression (AND), self-efficacy, external locus of control and interventions. Rationale Lack of research into midwife role in PTSD-PC. Population Age >18, 33-37wks pregnant, able to understand questionnaires.	Measure of PTSD PTSD diagnostic scale (PDS) (Foa, Cashman, Jaycox, & Perry, 1997) adapted for postnatal women, at 3 weeks and 3 months PC. Other scales used EPDS, MHLC scale, SES, IIS, SCIB.	Method Quantitative Cohort Prospective longitudinal study Subjective measures Various scales as listed in previous column Objective measures Demographics, prior trauma and birth interventions. Blinding used n/a. Confounding factors Accounted for in focus. Analysis Correlations (statistic not identified). Hierarchical multiple regressions.	Results Factors which contribute significantly to PTSD-PC: Low midwife support in women with prior trauma, or average, or above average level of birth interventions. Significant correlations: midwife support & internal locus of control; midwife support & external locus of control; midwife support & PTSD. Application to local population findings not generalisable to local population. Fit with other findings other findings: control related to interpersonal e.g. midwife support (Green & Baston, 2003). Discussion of findings Prioritise support rather than control Limitations observed High attrition rate. Low power, although sample size appropriate to find a difference. Unknown if correlation between midwife support and external control is due to bias or nature of challenging conditions	CASP rating High Implications for practice Calls for one-to-one supportive care being necessary to maximise positive psychological outcomes for women.
Harris and Ayers 2012 What makes labour and birth traumatic? A survey of intrapartum ‘hotspots’ UK	Sample size Purposive recruitment via internet support groups n=675. Sample represents defined population Childbearing women in UK. Drop-outs 699 recruited 24 excluded due to substantial missing data. Ethical Approval University research ethics committee. No mention of info given or consent obtained.	Focus Identifying frequency of hotspots, content of hotspots, cognitions and emotions during hotspots, and PTSD symptoms in women with traumatic birth experiences. Population Age > 18, had given birth, can read/write English fluently.	Measure of PTSD PTSD diagnostic scale (PDS) (Foa et al., 1997) adapted for postnatal women. Assessed at least 1 month PC. Other measures Cognitions and emotions during hotspots were measured using the ‘Initial reactions’ sub-scale of the ‘Potential Stressful Events Interview’ (adapted) (Resnick et al 1996).	Method Quantitative cross-sectional internet survey. Subjective measure Hotspots, questionnaire based on previous studies. Identifying hotspots of emotional distress in the trauma. Description of worst hotspot. Objective measures Mode of birth, parity, previous traumatic events, and time since birth. Blinding used n/a Data collection Online questionnaires. Confounding factors A range built into the regression models. Analysis Coding the description of the worst hotspots according to most prominent theme, based on coding schedule developed by the authors in a pilot study. Principal components analysis. Non-parametric tests (Kruskal-Wallis, Chi Square). Backward stepwise logistic regression.	Results 3 categories of worst hotspot: interpersonal difficulties (INT), obstetric compl (OBS), and neonatal compl (NEO). INT most freq content of worst hotspot: being ignored, lack of support, poor communication, (abandoned, under pressure), sig higher no. cases PTSD, sig distress, sig impairment, total symptoms, anger and conflict. INT gave 4xrisk PTSD vs NEO. OBS gave 3xrisk of PTSD vs NEO. Application to local population Mainly white women, not easy to generalise. Fit with other findings Only hotspot study. Findings re INT and lack support, consistent with previous findings in PTSD-PC and general PTSD. Discussion of findings suggests hotspots involve emotions / cognitions beyond DSM diagnostic criteria: Anger, failure, and negative effect (sadness and guilt). Limitations Retrospective design may make recall less accurate. Internet sampling, allows larger sample, but may limit range of postnatal women taking part.	CASP rating High Implications for practice Significance of interpersonal factors suggests reassurance, support, identifying and dealing with interpersonal difficulties, may prevent birth being experienced as traumatic. Future research needed around dissociation.
Menage 1993 Post-traumatic stress disorder in women who have undergone obstetric and/or gynaecological procedures: A consecutive series of 30 cases of PTSD UK	Sample size 30 Sample represents defined population Advertising for women volunteers. Research was described as investigating psychological stress caused by smear tests and vaginal examinations. Volunteers were age 18-60. Drop-outs 500 volunteered, 102 had a history which fulfilled criterion A of DSM-III-R, 30 fulfilled full PTSD criteria. Ethical approval Not specified	Focus Investigate whether the psychological stress caused by obstetric or gynaecological examinations could lead to PTSD. Population Women volunteers predominately from across UK.	Measure of PTSD PTSD Interview PTSD-I (Watson, Juba, Manifold, Kucala, & Anderson, 1991), designed for general PTSD	Method Mixed Subjective measures Perception of obstetrical or gynaecological experience using response scales. Women were also asked to relate their experience. Objective measures Demographic measures. For the 30 women with PTSD, history of previous trauma. Blinding used n/a Confounding factors Previous trauma was included, but no measure of previous PTSD. Analysis Descriptive statistics, 2-way mixed ANOVA.	Results: Factors significantly contributing to PTSD-PC: hostile doctor attitude, powerlessness, being ignored, adequacy of info given, lack of consent. Words used by women: Dehumanizing, degrading, distressing, dismissed, ignored, invaded, violated, brutal, excruciating, mutilated, held down, shouted at, humiliated, abused, terrifying, rape. Application to local population Limited to readership of advertising publications, a self-selected group, likely recognised stress in themselves. Fit with other findings Confirms other findings, especially re subjective experience. Discussion of findings Particularly important for women with previous sexual abuse, which may be undisclosed or repressed. Limitations Does not address other psychological issues.	CASP rating Moderate Implications for practice Medical profession to be aware that women need to be listened to more carefully, to determine their needs and perceptions, and to be mindful that there could be a history of sexual abuse. Medico-legal implications following trauma.
Nicholls and Ayers 2007 Childbirth-related post-traumatic stress disorder in couples: A qualitative study UK	Sample size 6 couples: 5 women and 3 men with PTSD-PC, 1 woman and 3 men without PTSD-PC. Time since birth event, 9 months to 2 years. Selection process Age >18, read/speak English fluently, one member of couple had to have experienced traumatic birth > 3 months ago, and one had to fulfil DSM-IV criteria for PTSD. Both had to be willing to be interviewed. Rationale Explore experience of both partners re experience of PTSD-PC and traumatic birth. Drop-outs 9 couples met incl. criteria, 6 consented. 3 partners did not consent. Ethical Approval Sussex university. Info provided, consent obtained.	Goal Exploring subjective experience of PTSD-PC in couples, but also explored experience of women and their partners during birth. Why important Need to extend knowledge re aetiology of PTSD-PC, the effect on women, men and parent-infant attachment Relevance Developing knowledge re couples’ perspectives on traumatic birth/PTSD-PC.	Measure of PTSD PTSD diagnostic scale (PDS) (Foa et al., 1997) adapted for postnatal women.	Method Qualitative Design Phenomenological Data collection Semi-structured interviews using 14 open questions. Collection technique Not explicit about whether hand or audio recorded. Transcribed. Rationale Exploring experience. Analysis Thematic analysis per individual. Reflexivity and reflection Not explicit, although independent coding by a 3^rd researcher.	Clear statement of findings ‘Quality of care’ (especially midwife attitude, information, environment) emerged as a major theme. Others were birth factors (pain, lack of choice, control, decision making, being restrained), perceived effect on relationship with partner/child. Consistent with other findings Lack of: control, communication, information, decision making. Discussion of findings Men reported more shock and helplessness. Women reported more fear, confusion, violation, dehumanisation, and anger. Authors highlight the emergence of ‘quality of care’ as a factor, which had not been asked about in the interview. Men and women differed in where they placed importance. Limitations No measure of pre-existing psychopathology and retrospective approach. Small sample, self-selected. Those who dropped out may have had more interpersonal difficulties.	CASP rating Moderate Value of the research Quality of care as major theme was particularly important as not specifically asked about, yet was important for all participants. Implications Need to increase midwife awareness of PTSD and contributing practices. Acknowledge and include partners, recognise risk of dissociation. Include partners in screening for PTSD, and consider families.
Nyberg et al. 2010Midwives’ experience of encountering women with posttraumatic stress symptoms after childbirth Sweden	Sample size 8 Selection process Midwives working in specialised clinics for women with PTS symptoms post childbirth. Rationale purposive sampling in one council area Drop-outs 15 invited, 8 consented and completed the interviews. Ethical approval Permission from the heads of the county’s councils responsible for the clinics. Ethics group at the dept. of health sciences, Luleå University of Technology. Info provided, consent sought.	Goal Exploring midwives’ experiences of encountering women with post traumatic stress symptoms after birth. Why important The only study to explore midwives experience of relating to women with PTSD-PC. Relevance Provides the midwives perspective, albeit in the postnatal period.	Measure of PTSD No measure of PTSD. Women attending clinics had been diagnosed with PTSD-PC.	Method Qualitative Design Phenomenological Data collection Semi-structured interviews. Collection technique Audio recorded and transcribed verbatim. Rationale Describe experience. Analysis Thematic content analysis. Reflexivity and reflection Not explicit, although all texts were read and coded a second time to check for appropriateness.	Clear statement of findings Midwives highlight major themes: meeting women with severe or frightening experiences, childbirth affected women’s lives, need to listen to and respond to women, be gentle with words, storytelling creates confirmation, enable women to express feelings, support women to give birth, lost confidence in giving birth, caesarean section does not solve problems. Some women had PTSD-PC after objectively normal childbirth. Women described: lack of control and respect, not being involved in decision making, and unmet expectations. Discussion of findings Midwives highlight need to reflect on their own attitude and use gentleness. Midwives desire access to mentoring and referral options for women. Limitations Small sample, but rich data. May need to explore from the women’s perspective.	CASP rating Moderate Value of the research Women’s needs to be respected and listened to seems to be one of the most important healthcare issues. Implications Need to raise quality of care for women with fear of childbirth, and support women to feel safe, well informed, and involved. Midwives should know women’s wishes. Need to develop further midwifery interventions to meet the needs of women with PTSD-PC.
Sorenson and Tschetter 2010 Prevalence of Negative Birth Perception, Disaffirmation, Perinatal Trauma Symptoms, and Depression Among Postpartum Women USA	Sample size 71 Sample represents defined population Women identified from archive of birth announcements in local paper, and who had current entry in local phone directory. Drop-outs 134 invited, 95 consented, 71 returned questionnaires Ethical approval Not specified	Focus Explore relationship between PTS symptoms, negative birth perception and QPI Population Women 6 months postpartum, who had recently given birthed locally.	Measure of PTSD Post traumatic childbirth stress inventory (PTCS) (Sorenson, 2003) (DSM-IV) Other measures Birth Perception Rating scale (BPRS), Quality of provider interaction inventory (QPI-I) Beck depression inventory II (BDI-II)	Method Quantitative. Subjective measures Perception of birth experience, quality of provider interaction Objective measures Demographic data. Blinding used n/a Confounding factors Analysis. Prior trauma or psychiatric wellbeing not assessed.	Results: Significant Correlations: QPI & PTS. QPI & birth perception. Birth perception & PTS. Provider affirmation more frequent than disaffirmation 15/21 affirm, 6/21 disaffirm Application to local population Sample mostly white and in stable relationships. Fit with other findings Theory of relationship between QPI and psychological status (Peplau, 1953). Discussion of findings QPI significantly correlated with PTS. QPI modifiable by midwife, whereas unmodifiable factors such as age, parity, mode of birth are not associated with PTS (statistics not provided). Limitations Sampling method may not allow accurate prevalence estimates. Correlations do not imply causal relationships.	CASP rating Moderate Implications for practice Raised questions re level of monitoring and enforcement of MIDWIFE ethic conduct. Poor QPI more readily tolerated than poor technical skills. Reinforce need for psychiatric liaison advanced practice nurses to support midwives to assess and interact with women appropriately. Reassuring that provider affirmation was more common than disaffirmation.
Tham et al. 2010 Experience of support among mothers with and without post-traumatic stress symptoms following emergency caesarean section Sweden	Sample size 42 women with PTSS, 42 women without PTSS, 6 months PC (note the authors refer to Post traumatic stress symptoms not full PTSD). Selection process Healthy women, Swedish or English speaking, delivered between 37-42 weeks, planned SVB. Rationale not specified Drop-outs 148 who met criteria were invited, 19 declined, 4 dropped out, 3 moved abroad.122 enrolled. Ethical issues addressed Local research ethics committee at Karolinska Institute, Stockholm. Info provided and consent obtained.	Goal Experience of support amongst mothers with and without PTSD following Emergency Caesarean section (EMCS). Why important Understanding difference in experience between women with and without PTSD-PC following EMCS. Relevance Explores birth experience in relations to PTSD-PC.	Measure of PTSD IES (Horowitz et al., 1979) to measure PTSD. 2 groups, no symptoms of PTSD and at least moderate symptoms of PTSD, using cut-off 19/20 points. Other measure made SoC scales completed at 2-3 days PC, reported in parent longitudinal study.	Method Qualitative. Design Secondary analysis of 84 women from a longitudinal study. Data collection PTSD assessed at 3 months PC. Collection technique Telephone Semi-structured interview at 6-7 months PC. Interviews based on a questionnaire plus supplementary questions to understand experience. Hand recorded then transcribed. Rationale To explore lived experience. Analysis Content analysis. Reflexivity and reflection Interviewer did not know women’s PTSS status at time of interview. Authors analysed texts separately until consensus was reached.	Clear statement of findings No figures presented. States majority women found midwife kind/supportive, contradicts findings: Women with PTS: several found midwife nervous; > ½ found midwife disinterested, lack support, communication; many felt lack of information, lack involvement in decisions, lack postpartum follow up (About ½ saw MW at 3 months); ⅓ experienced fear. Women without PTS: few found midwife uninterested or unsupportive. Almost all saw midwife at 3 months. New mums: majority: lack information. ⅓ each group: lack continuity. All desire counselling, only those with obj trauma, received this. Discussion of findings Midwives actions important, query worse care or women with PTS more sensitive, due to anxiety or history. Limitations Phone Interviews lack visual contact. Hand recording possible inaccuracy. No record of prior trauma or history of PTSD.	CASP rating Moderate Value of research Highlights importance of midwife’s actions/ inactions. Implications Treat all women as if vulnerable to trauma.
